On bar and column charts, you can adjust the distance between the sets of bars or columns (data sets); on charts where the data sets aren’t stacked, you can also adjust the distance between the each bars or columns (individual data sets). You can also apply shadows to individual data series or to the entire chart.
On bar and column charts that are not stacked, you can also opt to show the series names.
Select a bar or column chart.
Click Inspector in the toolbar, click the Chart inspector button, and then click Chart.
Do any of the following:
Change the space between bars or categories:
To change the space between bars, type a value (or click the arrows) in the “Gap between bars” field.
To change the space between categories (on unstacked charts), specify a value in the “Gap between sets” field.
The value is the percentage of the bar thickness. Decreasing the space between the bars makes them thicker. You can also move the pointer near a bar edge until it becomes a double-headed arrow, and then drag to make the bars thicker or thinner.
Add shadows:
To add shadows to individual bars, choose Individual from the Shadow pop-up menu.
To add shadows to each group of bars, choose Group from the Shadow pop-up menu.
To set shadow attributes, use the Graphic Inspector. See Adding Shadows for instructions.
To show series names, choose Show Series Names from the Choose Axis Options pop-up menu below Category Axis in the Axis pane of the Chart inspector. (This option isn’t available for stacked bar and column charts.)
